Workers in the transportation industry are at greater risk of an incorrect diet and sedentary behavior. The aim of our study was to characterize a population of professional bus drivers with regard to clinical and demographic variables, lipid profile, and the presence of cardiovascular risk factors. Data from 659 interstate bus drivers collected(More)
OBJECTIVE To define the profile of smokers who seek professional assistance through a smoking cessation program and to compare smoker profiles among males, females and elderly people. METHODS Two-hundred and three smokers were prospectively evaluated. The participants completed questionnaires related to smoking history, history of psychiatric disorders,(More)
BACKGROUND Chronic kidney disease (CKD) is one of the most serious public health problems. The increasing prevalence of CKD in developed and developing countries has led to a global epidemic. The hypothesis proposed is that patients undergoing dialysis would experience a marked negative influence on physiological variables of sleep and autonomic nervous(More)
OBJECTIVE To provide access to the results of a randomized cross-sectional study conducted by the Brazilian Center for Information on Psychotropic Drugs in 2001. METHODS This survey involved a random sample of individuals ranging from 12 to 65 years of age and residing in the 107 largest cities (over 200,000 inhabitants) in Brazil, which represented 27.7%(More)
The objective of this article was to describe a new method for assessing expiratory flow limitation during spontaneous breathing, using the negative expiratory pressure test to identify patients at risk for obstructive sleep apnea. Upper airway collapsibility is evaluated by measuring decreases in flow and in expired volume in the first 0.2 seconds after(More)
OBJECTIVE To determine the frequency of smoking among hospitalized patients in a general hospital, and to evaluate their profile. METHODS A random representative sample of 111 patients, classified as nonsmokers, former smokers or smokers, was evaluated. The smokers were submitted to the Fagerström test and measurement of expired carbon monoxide. Expired(More)
BACKGROUND Obesity is a major public health problem in both developed and developing countries alike and leads to a series of changes in respiratory physiology. There is a strong correlation between obesity and cardiopulmonary sleep disorders. Weight loss among such patients leads to a reduction in these alterations in respiratory physiology, but clinical(More)
BACKGROUND Obstructive sleep apnea (OSA) is a respiratory disease characterized by the collapse of the extrathoracic airway and has important social implications related to accidents and cardiovascular risk. The main objective of the present study was to investigate whether the drop in expiratory flow and the volume expired in 0.2 s during the application(More)
OBJECTIVE To evaluate radiologist agreement on the quantification of bronchiectasis by high-resolution computed tomography (HRCT). MATERIALS AND METHODS The HRCT scans of 43 patients with bronchiectasis were analyzed by two radiologists, who used a scoring system to grade the findings. Kappa (κ) values and overall agreement were calculated. RESULTS For(More)
